STUDY ON BENEFICIABILITY OF A LOW-GRADE REFRACTORY COPPER-MOLYBDENUM ORE

PU Cangfeng

Abstract

The beneficiability study was conducted because of the poor results of copper and molybdenum separation in actual practice of a low-grade refractory copper-molybdenum mine in Yunnan Province.The tests applied special separation process:copper-molybdenum bulk flotation,regrinding of bulk concentration,and then separation of copper and molybdenum.As a result,we had got better experimental index: copper recovery of 89.94%,copper concentrate grade of 23.04%,molybdenum recovery of 67.23% and molybdenum concentrate grade of 47.24%.
